I want to create a workflow in which users can upload a file to perform an analysis on the server. In order to do this i use a file upload node in conjuction with an xls reader node. I've tried both output variables from the upload node, but i always get this result:
Unable to execute workflow: Unable to execute workflow: java.lang.IllegalStateException: Subnode MetaNode 0 : 1 9:532 not executed
Can anyone please assist?
Thanks in advance.
